Exodus 29:28

28 and it hath been for Aaron and for his sons, by a statute age-during from the sons of Israel, for it [is] a heave-offering; and it is a heave offering from the sons of Israel, from the sacrifices of their peace-offerings -- their heave-offering to Jehovah.

Exodus 29:28 Meaning and Commentary

Exodus 29:28

And it shall be Aaron's and his sons by a statute for ever
from the children of Israel
That is, the shoulder, which seems particularly meant, though the breast also was theirs, which was at this time given to Moses, he being priest; and this was an everlasting statute and ordinance in all generations, as long as the priesthood of Aaron lasted, until the Messiah should come and put an end to it: and this the children of Israel were always to allow the priests; the shoulder, because Aaron bore their names before the Lord upon his shoulders, for a memorial; and the breast for a like reason, because he bore their names in the breastplate of judgment upon his heart, and their judgment also before the Lord continually, ( Exodus 28:12 Exodus 28:29 Exodus 28:30 ) ,

for it is an heave offering:
it is lifted up to the Lord, and therefore is given to his priest:

and it shall be an heave offering from the children of Israel of the
sacrifice of their peace offerings, [even] their heave offering unto
the Lord:
it being heaved up and given to the priest, it was reckoned an offering to the Lord, and was accepted by him as a peace offering; and it was an emblem of the lifting up of their hearts to God, and of the going up of the affections and desires of their souls to him, and of their serving and worshipping him in spirit and in truth, who is a spirit, and was their Father in heaven, to whom their eyes, hearts, and hands, were to be lifted up.

Exodus 29:28 In-Context

26 `And thou hast taken the breast from the ram of the consecration which [is] for Aaron, and hast waved it -- a wave-offering before Jehovah, and it hath become thy portion;
27 and thou hast sanctified the breast of the wave-offering, and the leg of the heave-offering, which hath been waved, and which hath been lifted up from the ram of the consecration, of that which [is] for Aaron, and of that which [is] for his sons;
28 and it hath been for Aaron and for his sons, by a statute age-during from the sons of Israel, for it [is] a heave-offering; and it is a heave offering from the sons of Israel, from the sacrifices of their peace-offerings -- their heave-offering to Jehovah.
29 `And the holy garments which are Aaron's, are for his sons after him, to be anointed in them, and to consecrate in them their hand;
30 seven days doth the priest in his stead (of his sons) put them on, when he goeth in unto the tent of meeting, to minister in the sanctuary.
